Background: Up to know, limited and contradictory results have been published about the role of prognostic values of lipid profile and proprotein convertase subtilisin/kexin type 9 (PCSK9) in Parkinson’s disease (PD). The aim of the present study is to investigate the role of lipid profile and PCSK9 in patients with PD and compare it with healthy individuals.Methods: In this case-control study, 31 individuals diagnosed with PD were compared with 31 healthy individuals. The lipid profile and PCSK9 of research participants were measured and the resulting data were analyzed using SPSS software. The P-values smaller than 0.05 were considered significant.Results: The mean age of participants in the PD and control group was 56.9 ± 8.8 and 53.7 ± 10.1 years, respectively (P > 0.050). 27 individuals (87.1%) in the PD group and 13 individuals (41.9%) in the control group were men. Low-density lipoprotein (LDL) level (84.2 ± 24.9 ml/dl vs. 105.5 ± 16.8, P < 0.001), high-density lipoprotein (HDL) level (45.5 ± 8.7 ml/dl vs. 51.1 ± 9.5 ml/dl, P < 0.001), and total cholesterol (155.3 ± 31.2 ml/dl vs. 192.8 ± 32.5 ml/dl, P < 0.001) were lower and triglyceride (TG) level was higher in the PD group (133.3 ± 79.3 ml/dl vs. 131.2 ± 58.6 ml/dl, P = 0.900) compared with the control group. PCSK9 level was higher in the PD group, but no significant difference was found (141.6 ± 70.0 vs. 129.7 ± 51.0 ng/ml, P = 0.500) compared to healthy subjects. Moreover, there was no relation between PCSK9 and severity of PD. Conclusion: Our findings showed that individuals with PD had lower levels of HDL, LDL, and total cholesterol compared with the control group. However, higher concentrations of PCSK9 were observed in patients with PD compared with healthy volunteers.

Background: The accuracy of current laboratory and imaging studies for diagnosis and monitoring of Parkinson’s disease (PD) severity is low and diagnosis is mainly dependent on clinical examination. Proton magnetic resonance spectroscopy (MRS) is a non-invasive technique that can assess the chemical profile of the brain. In this study, we evaluated the utility of proton MRS in diagnosis of PD and determination of its severity.Methods: Patients with PD and healthy age-matched controls were studied using proton MRS. The level of N-acetylaspartate (NAA), total creatine (Cr), and total choline (Cho), and their ratios were calculated in substantia nigra (SN), putamen (Pu), and motor cortex. PD severity was assessed by the Unified Parkinson’s Disease Rating Scale (UPDRS) and the Hoehn and Yahr scale.Results: Compared to 25 healthy controls (18 men, age: 59.00 ± 8.39 years), our 30 patients with PD (24 men, age: 63.80 ± 12.00 years, 29 under treatment) showed no significant difference in the metabolite ratios in SN, Pu, and motor cortex. Nigral level of NAA/Cr was significantly correlated with total UPDRS score in patients with PD (r = -0.35, P = 0.08). Moreover, patients with PD with Hoehn and Yahr scale score ≥ 2 had a lower NAA/Cr level in SN compared to patients with a lower stage.Conclusion: This study shows that 1.5 tesla proton MRS is unable to detect metabolite abnormalities in patients with PD who are under treatment. However, the NAA/Cr ratio in the SN might be a useful imaging biomarker for evaluation of disease severity in these patients.

Background: Nowadays, many neurological conditions, including Parkinson’s disease (PD), are treated with deep brain stimulation (DBS). Life-threatening consequences can occur from DBS hardware failure or sudden implantable pulse generator (IPG) battery depletion. This issue may potentially worsen in concomitance with medical or infectious conditions, requiring stronger emergency management. Methods: We present here a 58 year-old PD patient with DBS, whose IPG replacement surgery was complicated by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and we report management of this patient along with recommendations for patients with similar situation. Results: As the newly-emerged coronavirus disease 2019 (COVID-19) is now announced to be pandemic, new protocols and specific measures for each individual group of patients with chronic diseases seem obligatory. Regarding our recent experience with a patient suffering from PD, on DBS treatment, who needed hospitalization, we felt useful to share our experience as a recommended protocol for similar patients in the time of current pandemic. Conclusion: Close monitoring of laboratory and clinical signs should be warranted in patients with PD awaiting IPG replacement in order to be prepared in these novel conditions that may precipitate an akinetic crisis/dystonic storm and to prevent life-threatening complications during the current pandemic.
